Description

工作機械のレベル出し構造Machine tool leveling structure
　本発明は、レベル出しの再現を簡単に行うことができるようにした工作機械のレベル出し構造に関する。 The present invention relates to a leveling structure of a machine tool that enables easy reproduction of leveling.
　工作機械は、出荷前に製造工場で組み立てられて性能検査などが行われる。その際、主軸装置やタレット装置などの駆動装置が組み付けられるベッドについてレベル出しが行われる。その後、分解されて搬送された工作機械は、納入先の工場に据え付ける場合に同じ性能がでるようにレベル出しが行われる。この点、下記特許文献１には、ベッド上に一対のガイドレールが平行に敷設され、特に上面が高精度に加工され、そこに水準器を載置することによってレベル出しを行う構成が開示されている。具体的には、一方のガイドレール端部の第１基準面と、他方のガイドレール端部の第２基準面とに水準器の両端部が置かれ、ベッドのＸ方向におけるレベル出しが行われる。また、他方のガイドレールの第３基準面に水準器が置かれてベッドのＺ方向におけるレベル出しが行われる。 Machine tools are assembled at the manufacturing plant and inspected for performance before shipping. At that time, the level is set for the bed to which the drive device such as the spindle device and the turret device is assembled. After that, the machine tools that have been disassembled and transported are leveled so that the same performance can be obtained when they are installed in the factory to which they are delivered. In this regard, Patent Document 1 below discloses a configuration in which a pair of guide rails are laid in parallel on a bed, the upper surface is particularly processed with high precision, and a level is placed on the upper surface to perform leveling. ing. Specifically, both ends of the spirit level are placed on the first reference plane at the end of one guide rail and the second reference plane at the end of the other guide rail, and leveling is performed in the X direction of the bed. .. Further, a spirit level is placed on the third reference plane of the other guide rail to level the bed in the Z direction.

　しかし、前記従来例は、水準器を置く箇所がガイドレール上であるため、そこに可動体が組み付けられてしまうとレベル出しができなくなってしまう。このように、水準器を置くレベル出しの位置をベッド上に設けてしまうと、納入先の工場に搬送する段階でガイドレール上に装置が組み付けられているようなこともある。そうした場合には水準器を置くことができなくなってしまい、他の箇所に水準器を置いたレベル出しをしなければならなくなる。すなわち、生産工場と同じレベル出しが再現できなくなってしまい、不十分な状態で工作機械を組み立てることになり、加工精度の低下や予期せぬ負荷が不具合を生じさせことにもなる。 However, in the above-mentioned conventional example, since the place where the spirit level is placed is on the guide rail, if a movable body is assembled there, it becomes impossible to set the level. In this way, if the leveling position where the spirit level is placed is provided on the bed, the device may be mounted on the guide rail at the stage of transporting to the delivery destination factory. In such a case, you will not be able to place a spirit level, and you will have to put a spirit level in another place to level it. That is, the same leveling as in the production factory cannot be reproduced, and the machine tool is assembled in an inadequate state, resulting in a decrease in machining accuracy and an unexpected load causing a problem.
　そこで、本発明は、かかる課題を解決すべく、再現性の高い工作機械のレベル出し構造を提供することを目的とする。 Therefore, an object of the present invention is to provide a highly reproducible leveling structure for a machine tool in order to solve such a problem.
　本発明の一態様における工作機械のレベル出し構造は、ベッド上に所定の加工装置を搭載した工作機械に関するものであって、前記ベッドの任意の側面部分に設けられた組付け部と、前記組付け部に固定される水準器置台と、前記組付け部に姿勢を調整して固定され前記水準器置台の固定基準となる基準ブロックとを有する。 The leveling structure of a machine tool according to one aspect of the present invention relates to a machine tool in which a predetermined processing device is mounted on a bed, and has an assembly portion provided on an arbitrary side surface portion of the bed and the assembly. It has a spirit level pedestal fixed to the attachment portion and a reference block that is fixed to the assembly portion by adjusting its posture and serves as a fixing reference for the spirit level pedestal.
　前記構成によれば、ベッドの任意の側面部分に組付け部が設けられた、そこに姿勢を調整して固定された基準ブロックに基づいて水準器置台を固定することにより、一旦レベル出しが行われたベッドを、異なる場所でもレベル出しする場合に、先に行ったレベル出しを再現することができる。 According to the above configuration, the leveling is once performed by fixing the spirit level stand based on the reference block in which the assembling portion is provided on an arbitrary side surface portion of the bed and the posture is adjusted and fixed there. If you want to level the broken bed in different places, you can reproduce the previous leveling.

　本発明に係る工作機械のレベル出し構造の一実施形態について、図面を参照しながら以下に説明する。図１は、本実施形態の工作機械について主要な構成を示した斜視図であり、レベル出し構造部分が拡大して示されている。図２は、工作機械のベッドを下から見た斜視図であり、同じくレベル出し構造部分が拡大して示されている。本実施形態の工作機械は、ＮＣ旋盤とマシニングセンタの両方の機能を持つようにした複合加工機１である。具体的には、ワークＷを把持する第１ワーク主軸装置３および第２ワーク主軸装置４と、複数の工具Ｔを有する第１タレット装置５および第２タレット装置６が、それぞれ左右対称に配置された対向２軸旋盤であり、加えて機体中央には工具主軸装置２が設けられている。 An embodiment of the leveling structure of the machine tool according to the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a main configuration of the machine tool of the present embodiment, and the leveling structure portion is enlarged and shown. FIG. 2 is a perspective view of the bed of the machine tool as viewed from below, and the leveling structure portion is also enlarged and shown. The machine tool of the present embodiment is a multi-tasking machine 1 having both functions of an NC lathe and a machining center. Specifically, the first work spindle device 3 and the second work spindle device 4 for gripping the work W, and the first turret device 5 and the second turret device 6 having a plurality of tools T are arranged symmetrically, respectively. It is a two-screw lathe facing each other, and in addition, a tool spindle device 2 is provided in the center of the machine body.
　一対の第１および第２ワーク主軸装置３，４は、それぞれ主軸台１２のスピンドルチャック機構１１が組み付けられ、スピンドルモータ１３の駆動によって回転し、把持したワークＷに加工時の位相決めや所定速度での回転が与えられる。主軸台１２やスピンドルモータ１３は主軸スライド１４に搭載され、ベッド７上を機体幅方向であるＺ軸方向に移動するよう構成されている。前傾したベッド７の前部にはＺ軸に平行なガイドレール１５が固定され、そこを摺動する主軸スライド１４に対して主軸モータの回転運動を直進運動に変換するボールネジ機構が設けられている。 The pair of first and second work spindle devices 3 and 4 are respectively assembled with the spindle chuck mechanism 11 of the headstock 12, rotated by the drive of the spindle motor 13, and the gripped work W is subjected to phase determination and a predetermined speed at the time of machining. Given the rotation at. The headstock 12 and the spindle motor 13 are mounted on the spindle slide 14 and are configured to move on the bed 7 in the Z-axis direction, which is the width direction of the machine body. A guide rail 15 parallel to the Z axis is fixed to the front part of the bed 7 tilted forward, and a ball screw mechanism for converting the rotational motion of the spindle motor into a linear motion is provided for the spindle slide 14 sliding there. There is.
　次に、第１タレット装置５および第２タレット装置６は、第１ワーク主軸装置３と第２ワーク主軸装置４の後ろに位置し、割出し用サーボモータ１６の回転制御によってタレット１７に装着された工具Ｔ（タレット工具）の旋回割出しが行われる。そして、工具ＴをワークＷに対する加工位置に移動させるため、タレット１７がＺ軸に直交する機体前後及び上下の２方向に移動するよう、ガイドレールによる移動機構にボールネジを使用した駆動機構が設けられている。 Next, the first turret device 5 and the second turret device 6 are located behind the first work spindle device 3 and the second work spindle device 4, and are mounted on the turret 17 by the rotation control of the indexing servomotor 16. The turning index of the tool T (turret tool) is performed. Then, in order to move the tool T to the machining position with respect to the work W, a drive mechanism using a ball screw is provided as a movement mechanism by the guide rail so that the turret 17 moves in two directions of front and back and up and down of the machine body orthogonal to the Z axis. ing.
　工具主軸装置２は、主軸用サーボモータや工具スピンドルが内蔵されたビルトインタイプの主軸ヘッド１８を有し、鉛直なＸ軸方向に移動可能な主軸スライド１９に搭載されている。そして、主軸スライド１９はベーススライド２０に搭載され、機体前後方向の水平なＹ軸方向に移動可能な構成が設けられている。主軸ヘッド１８は、加工内容に応じて工具Ｔ（主軸ヘッド工具）の取り換えが可能であり、Ｙ軸に平行はＢ軸を中心に回転するよう構成されている。 The tool spindle device 2 has a built-in type spindle head 18 having a built-in servomotor for the spindle and a tool spindle, and is mounted on a spindle slide 19 that can move in the vertical X-axis direction. The main axis slide 19 is mounted on the base slide 20 and is provided with a configuration capable of moving in the horizontal Y-axis direction in the front-rear direction of the machine body. The spindle head 18 can be replaced with a tool T (spindle head tool) according to the machining content, and is configured to rotate about the B axis in parallel with the Y axis.
　複合加工機１は、機体前後方向の寸法を抑えることにより省スペース化を目的に構成されたものであり、スラントタイプのベッド７は機体幅方向の寸法が大きくなっている。そのベッド７上を移動する各装置２，３，４，５，６は、いずれもガイドレールに沿った直線移動する構成を有しているが、特に第１および第２ワーク主軸装置３，４は、その移動距離が他に比べて長くなっている。そのため、ベッド７のレベル出しは、ガイドレール１５が固定される前側において行われるようにすることが好ましい。 The compound processing machine 1 is configured for the purpose of saving space by suppressing the dimensions in the front-rear direction of the machine, and the slant type bed 7 has a large size in the width direction of the machine. Each of the devices 2, 3, 4, 5, and 6 moving on the bed 7 has a configuration of linearly moving along the guide rail, and in particular, the first and second work spindle devices 3, 4 Has a longer travel distance than others. Therefore, it is preferable that the leveling of the bed 7 is performed on the front side where the guide rail 15 is fixed.
　ところで、複合加工機１は、出荷前の組み立てにおいてレベル出しが行われるが、納入先の工場設置時でも同じレベル出しが再現できなければならない。そのためには、出荷前のレベル出し、すなわち水準器が置かれる位置および状態が、納入先の工場設置時においても同様であることが望ましい。しかし、ある程度組み付けが済んだ状態で工場に搬入されるようなこともある。よって、前記従来例のように装置が組み付けられるガイドレール上でレベル出し行うことは好ましくない。 By the way, the multi-tasking machine 1 is leveled in the assembly before shipping, but the same leveling must be able to be reproduced even when the delivery destination factory is installed. For that purpose, it is desirable that the leveling before shipment, that is, the position and state where the spirit level is placed, is the same even when the factory is installed at the delivery destination. However, it may be delivered to the factory after being assembled to some extent. Therefore, it is not preferable to perform leveling on the guide rail to which the device is assembled as in the conventional example.
　そこで、本実施形態のレベル出し構造は、上に重なるものがないベッド７の側面であって、特にガイドレール１５に近い前面部分に３箇所設けられている。そのレベル出し構造は、ベッド７の前面に対して溶接などによって組付けプレート３１が一体に固定された組付け部が構成され、そこに水準器２８を載せるための水準器置台３２が着脱可能に取り付けられている。図３は、組付けプレート３１から水準器置台３２を外した状態のレベル出し構造を示した斜視図である。 Therefore, the leveling structure of the present embodiment is provided at three places on the side surface of the bed 7 where there is no overlap, especially on the front portion near the guide rail 15. The leveling structure comprises an assembling portion in which the assembling plate 31 is integrally fixed to the front surface of the bed 7 by welding or the like, and the spirit level 32 for mounting the spirit level 28 can be attached and detached there. It is attached. FIG. 3 is a perspective view showing a leveling structure in a state where the level 32 is removed from the assembly plate 31.
　長方形の組付けプレート３１は、下辺に沿って水平な受け部３１１が突き出しており、その受け部３１１を基準にして水準器置台３２などが組付けられている。水準器置台３２は、受け部３１１との間に調整用スペーサ３５が一体の基準ブロック３３を挟み込むようにして固定されている。基準ブロック３３は、図示するような直方体形状の横長ブロックであり、正面から２本のボルト３６によってタップが切られた組付けプレート３１側に締め付け固定される。そして、基準ブロック３３には下面側左右両端部に切欠きの段差部３３１が形成され、そこに重ねられた調整用スペーサ３５が下からネジ止めされている。 The rectangular assembly plate 31 has a horizontal receiving portion 311 protruding along the lower side, and a spirit level 32 or the like is assembled with the receiving portion 311 as a reference. The spirit level 32 is fixed so that the adjusting spacer 35 sandwiches the reference block 33 integrally with the receiving portion 311. The reference block 33 is a horizontally long block having a rectangular parallelepiped shape as shown in the figure, and is fastened and fixed to the assembly plate 31 side tapped by two bolts 36 from the front. The reference block 33 is formed with stepped portions 331 having notches at both left and right ends on the lower surface side, and the adjusting spacer 35 superposed therewith is screwed from below.
　調整用スペーサ３５は、基準ブロック３３の下面よりも突き出しているため、受け部３１１に調整用スペーサ３５が当てられた位置が、組付けプレート３１に固定された基準ブロック３３の取り付け位置になる。基準ブロック３３は、受け部３１１よりも前方に突き出しており、その突き出し量は１０ｍｍ程度である。水準器置台３２は、この基準ブロック３３に当てた状態で位置決めされ、組付けプレート３１に固定される。 Since the adjustment spacer 35 protrudes from the lower surface of the reference block 33, the position where the adjustment spacer 35 is applied to the receiving portion 311 is the mounting position of the reference block 33 fixed to the assembly plate 31. The reference block 33 protrudes forward from the receiving portion 311 and the amount of protrusion thereof is about 10 mm. The spirit level 32 is positioned in contact with the reference block 33 and fixed to the assembly plate 31.
　水準器置台３２は、水準器２８を置くための載置部３２１と、その載置部３２１から直角に折れた固定部３２２とがあり、固定部３２２は、基準ブロック３３を挟んだ両側に設けられ、ボルト３７を通すダルマ孔が形成されている。そして、この水準器置台３２は、ベッド７の鉛直な前面に対して、載置部３２１が直交した水平方向に突き出すようにして組付けプレート３１に固定される。その際、水準器置台３２の載置部３２１は、基準ブロック３３に当てられることにより姿勢調整が行われる。その調整は、左右の調整用スペーサ３５の厚さを研磨することにより、基準ブロック３３の姿勢を変化させることで可能になっている。 The level 32 has a mounting portion 321 for placing the level 28 and a fixing portion 322 bent at a right angle from the mounting portion 321. The fixing portions 322 are provided on both sides of the reference block 33. A Dharma hole is formed through which the bolt 37 is passed. Then, the level 32 is fixed to the assembling plate 31 so that the mounting portion 321 protrudes in the horizontal direction orthogonal to the vertical front surface of the bed 7. At that time, the posture of the mounting portion 321 of the spirit level stand 32 is adjusted by being applied to the reference block 33. The adjustment is possible by changing the posture of the reference block 33 by polishing the thickness of the left and right adjustment spacers 35.
　こうしたレベル出し構造を備えた複合加工機１は、出荷前の組み立てにおいて、ガイドレール１５に対する水平軸の真直度などのレベル出し作業が行われる。そして、ベッド７についてレベル出しが完了した後は、図１に示すように水準器置台３２の上に水準器２８を置いた再現用の調整作業が行われる。つまり、レベル出しされたベッド７に取り付けた水準器置台３２のレベル出しが行われ、水準器置台３２の水準が出ていない場合には、水準器置台３２の傾きを微調整して水準器２８の値がゼロになるようにする。具体的には、調整用スペーサ３５を研磨することにより、組付けプレート３１の受け部３１１に対して基準ブロック３３の左右の傾きの調整が行われる。 In the multi-tasking machine 1 equipped with such a leveling structure, leveling work such as straightness of the horizontal axis with respect to the guide rail 15 is performed in assembly before shipment. Then, after the leveling of the bed 7 is completed, the adjustment work for reproduction is performed by placing the level 28 on the level 32 as shown in FIG. That is, the level of the level 32 attached to the leveled bed 7 is leveled, and if the level of the level 32 is not reached, the inclination of the level 32 is finely adjusted and the level 28 is used. Make sure that the value of is zero. Specifically, by polishing the adjusting spacer 35, the left-right inclination of the reference block 33 is adjusted with respect to the receiving portion 311 of the assembly plate 31.
　こうした調整作業により水準器２８の値がゼロになった水準器置台３２は、ベッド７のレベル出し状態に対応しているため、これを水準器置台３２のレベル出し状態という。その後、ベッド７上には第１および第２ワーク主軸装置３，４のほか第１および第２タレット装置５，６や工具主軸装置２など組み付けられが行われるが、複合加工機１は更に図示していない自動工具交換装置やワーク自動搬送装置、さらには加工屑排出装置なども組み付けられることによって完成する。その際、ベッド７の前面に突き出している水準器置台３２が邪魔になるため、基準ブロック３３を残したまま水準器置台３２が一旦取り外される。 Since the spirit level 32 whose value of the spirit level 28 became zero due to such adjustment work corresponds to the leveling state of the bed 7, this is called the leveling state of the spirit level 32. After that, in addition to the first and second work spindle devices 3 and 4, the first and second turret devices 5 and 6 and the tool spindle device 2 are assembled on the bed 7. It will be completed by assembling an automatic tool changer, an automatic workpiece transfer device, and a machining waste discharge device, which are not shown. At that time, since the spirit level 32 protruding from the front surface of the bed 7 becomes an obstacle, the spirit level 32 is temporarily removed while leaving the reference block 33.
　次に、納入先の工場に設置する据付作業を行う場合には、レベル出しのために再びベッド７の前面に水準器置台３２が取り付けられる。このときベッド７の組付けプレート３１には調整済みの基準ブロック３３は固定されたまま残っているので、水準器置台３２は、その基準ブロック３３に当てた位置決めによって前述したレベル出し状態が再現される。そのため、水準器置台３２に水準器２８をおいてレベル出しすることにより、ガイドレール１５などの水平軸の真直度を出したベッド７におけるレベル出しが行われる。その後、再び水準器置台３２を取り外して自動工具交換装置などを組み付けることによって複合加工機１を完成させる。 Next, when performing the installation work to be installed in the factory of the delivery destination, the spirit level 32 is attached to the front of the bed 7 again for leveling. At this time, since the adjusted reference block 33 remains fixed to the assembly plate 31 of the bed 7, the spirit level 32 is reproduced in the above-mentioned leveling state by positioning the reference block 33. To. Therefore, by placing the spirit level 28 on the spirit level 32 and leveling it, the leveling is performed on the bed 7 in which the horizontal axis such as the guide rail 15 is straightened. After that, the spirit level 32 is removed again and an automatic tool changer or the like is attached to complete the multi-tasking machine 1.
　よって、本実施形態では、水準器２８を置くためのレベル出し構造の位置を、従来例で示したガイドレールのように後に装置などが組み付けられる場所とはせず、組み付けに影響を受けないベッド７の側面部とした。そのため、納入後に複合加工機１を組み立てる場合にも、水準器置台３２を組付けプレート３１の同じ位置で、基準ブロック３３に従った同じ姿勢で固定される。そして、その水準器置台３２の上で水準器２８によるレベル出しを行うことにより、出荷前の組み立てにおいて行われたベッド７のレベル出しが再現できる。 Therefore, in the present embodiment, the position of the leveling structure for placing the level 28 is not set to the place where the device or the like is to be assembled later like the guide rail shown in the conventional example, and the bed is not affected by the assembly. It was the side surface of 7. Therefore, even when the multi-tasking machine 1 is assembled after delivery, the spirit level 32 is fixed at the same position on the assembly plate 31 and in the same posture according to the reference block 33. Then, by leveling with the level 28 on the level 32, the leveling of the bed 7 performed in the pre-shipment assembly can be reproduced.
　また、本実施形態のレベル出し構造は、水準器置台３２が取り外し可能な構成であるため、レベル出し作業以外の場合には取り外すことによって邪魔にならない。そして、基準ブロック３３は、調整した状態のまま固定されているため、その基準ブロック３３に従って水準器置台３２を再度取り付けた場合に、先にレベル出しした状態の再現性が高い。 Further, since the leveling structure of the present embodiment has a structure in which the spirit level 32 is removable, it does not get in the way by removing it except for the leveling work. Since the reference block 33 is fixed in the adjusted state, the reproducibility of the previously leveled state is high when the spirit level 32 is reattached according to the reference block 33.
　本発明の一実施形態について説明したが、本発明はこれらに限定されるものではなく、その趣旨を逸脱しない範囲で様々な変更が可能である。
　例えば、前記実施形態では、ベッド７の側面であって特にガイドレール１５に近い前面部分にレベル出し構造を設けたが、組付け後でも邪魔にならない側面部であれば他の箇所にレベル出し構造を設けるようにしてもよい。 Although one embodiment of the present invention has been described, the present invention is not limited to these, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the leveling structure is provided on the side surface of the bed 7 and particularly on the front portion close to the guide rail 15, but if the side surface portion does not get in the way even after assembly, the leveling structure is provided at another location. May be provided.
